Immediate advice, please!

I have a bit of a dilemma. My pre-dinner reading was 3.6 just now and the dinner I was literally about to eat consisted of a large pile of raw spinach leaves, cucumber, a large juicy salmon fillet, small portion of cheese and spoonful of mayo. So IF I had injected insulin, it would have made me go even lower and as there would not be much in the dinner for the insulin to work on, I could see no point in having any. Although, in theory, this sounds great,(isn't it what we all dream of) I'm really nervous about not having had it.I use a long-acting and short acting insulin mix (Novomix 30) but am unsure of if I'll be okay from now, right through the night without any insulin.
Should I just monitor my readings every few hours and see how I go or am I doing something too risky? What if I need to eat something later, if readings dip further, do I then have some insulin?

I was going to go for a walk, as it's a nice evening but know that would bring me down even lower. Any suggestions folks?

Thanks, Sarah. I've just taken another reading and it's still 3.6.Okay, if I have something small to correct the hypo but don't have any carbs though for insulin to work on, won't my readings just level out? I'm sorry to ask so many questions but I don't want to mess up and start my readings swinging like they used to before I cut down on carbs.

None tonight. I'm just unsure of how much to have with reading so low to begin with. (I've had a small piece of stem ginger in syrup to correct hypo.)

Thanks. I'll take another reading before bed and think I'll do as you and Sarah suggest, have a small amount of carbs with small amount of insulin to avoid any trouble in the night. Seems almost going against what I'm trying to do but I've not the courage to go without altogether.

Right, just tested again as I had a headache and it's jumped to 7.6. Now taken 4 units of my insulin and had a slice of seeded bread with cheese spread. Thanks for your advice guys.All good fun!
